Things to considerStrength of the structure
Compatibility of the structure and GA
Demands on production
Brackets and openings
Classification standards
Drawings

Strength of the structureCalculated in Conceptual Design
Are the results reliable
Is there a proper way to do calculations for wooden ships? What about catamarans? If new methods are found: compare to previous
results
Find people who know more about the subject

Compatibility with GAWill only concern the machinery in the hull
Room for everything without making areas too heavy, e.g. at batteries?
Is there room for enough watertight bulkheads? If not, can the machinery be moved?Will this affect the strength considerably?

Demands on productionConsidered in Shipyard engineering
The machinery will be bought from a subcontractorMost work on the wooden frameConnecting all the machineryWiring the batteries
What needs to be checked during production?Good joints?Avoid bending of the wood?Etc.

Brackets and openingsSimple construction
No water, heating or A/C in the hullHydrogen pipes, cooling system and wiring
Where should the openings be for an effective design?
Access hatches from the passenger area
How will large cable bundles (especially from the batteries) affect e.g. watertight bulkheads?

Classification standardsAre there classification standards for wooden
catamaran ferries? If not, what standards can be used?
Standards for wooden ships
Standards for catamarans
This area will probably be unclear, at this point we need to make our own decisions on what actually fulfills all standards

DrawingsFrom CAD course
CAD model of the ship, but with assumed steel structure
Can’t be used here
Enough time to make a new model with our wooden structure?Probably not
The simple design means that new, separate drawings might be the easiest solution

Work plan and problemsStrength calculations most important
Find proper standards, if available
GA compatibility, production, openings, etc. should be quick
Solution for the needed drawings
Work plan:One person concentrates on the strength
calculationsThe other takes care of the rest

Final work plan and expectations
Ran Strength calculation (check old ones, make new if needed), drawings A lot of calculations
Tomas GA compatibility, production, openings, standards, drawings Lots of writing, searching for sources
(Initial plan, we will help each other at the end anyway)
The strength calculations can be a problem, especially knowing if results are correct. The rest should mostly be checking previous work
Personal deadlines: 17.10 Gives time for compiling and checking problems
